PDF Conversion Quality

Smallpdf is dependable for everyday PDF operations such as compress, merge, split, and PDF-to-Office conversions. FastlyConvert is similarly capable for core PDF use and becomes more useful when you chain additional non-PDF tasks after conversion.

In short: for pure PDF workflows, either can work. For mixed content pipelines that include audio/video assets, FastlyConvert reduces tool hopping.

Privacy & Security

FastlyConvert positions itself as browser-first and states automatic file deletion after 24 hours, which can be attractive for teams trying to minimize cloud exposure time.

Smallpdf provides its own privacy commitments and security documentation. For regulated environments, compare data retention, processing location, and account controls directly on both official policy pages.

Pricing

Both tools have free access with limitations and optional paid upgrades. Since plans and limits can change frequently, avoid relying on static blog screenshots.

The better value depends on your use pattern: PDF-only volume processing vs broader daily conversion needs that include media and transcription tasks.

Format Support

Smallpdf is PDF-first by design. That is ideal if you only convert and manage documents.

FastlyConvert adds image, video, and audio formats plus AI transcription. This is the biggest differentiator if your workflow includes meeting recordings, voice notes, or media clips alongside PDFs.

User Experience

Smallpdf has a focused and polished PDF workflow experience, especially for users who just need document tasks done quickly.

FastlyConvert keeps a consistent interface across multiple categories and supports 7 languages, which can be helpful for global teams handling different file types.

When to Use Each Tool

Choose FastlyConvert if:

  • You need one tool for PDF, video, audio, image conversion, and transcription.
  • You prefer a browser-first privacy posture with 24-hour file auto-delete.
  • You want to avoid juggling separate apps for document and media tasks.

Choose Smallpdf if:

  • Your team mainly performs PDF-only operations every day.
  • You prefer a tightly focused PDF product with minimal extra categories.
  • You do not currently need AI transcription or media conversion workflows.

Practical tip: Before subscribing, compare one week of your real tasks. Count how often you touch non-PDF files; that single metric usually makes the decision obvious.
